I made a vegan ice cream pie for my mother-in-law's b-day...it was heaven.
It consisted of (by layer)
chocolate cookie crust
chocolate ice cream (soy delicious)
chocolate covered pretzels
chocolate-peanut butter ice cream (soy delicious)
chocolate cookies
chocolate syrup
caramel sauce
peanuts
pretzels
(I put it all in a springform pan and put in freezer)
